I think you need to carry on researching before you start buying parts that you don't need. If you are not installing a tremolo, then you don't need anything relating to it such as the trem block, which is actually part of a trem. If your goin to use a hard tail bridge find some build threads where they are used to see how they are set up, strung, grounded etc. it's all on here. The reason those pre-cut bodies have the trem route is because strats by definition come with a tremolo.
